Accelevation Holdings raised $540 million in its IPO, pricing shares at $18, below the marketed range of $20-$24. The data center infrastructure company, backed by Olympus Partners, is valued at approximately $4 billion. Despite strong demand for AI-related stocks, the discounted price reflects investor caution on valuations. Accelevation reported revenue growth to $437.5 million and a $1.1 billion backlog, though customer concentration remains a risk. Shares begin trading Wednesday on Nasdaq under ticker ACCV.
